Description
Technical field
The present invention relates to orthodontic technical field, particularly a kind of correction medical bracket.
Background technology
At present, in the orthodontic treatment process of Buccodental, orthodontic bracket is fixed on facing, arch wire is through the archwire slot (having another name called square shred groove) on bracket, and by ligation rubber ring or steel ligature by direct for arch wire ligation in bracket tie wings, the corrective force of arch wire is delivered to tooth by bracket, makes tooth produce the movement of expection, to reach the object correcting tooth.
Because ligation rubber ring used at present or steel ligature ligation are in the tie wings of bracket, directly force in arch wire, larger pressure is created to arch wire, hamper the normal movement of arch wire, thus shadow is to the correction effect of tooth.At present, market also there is multiple locking bracket, had the active and large series of passive type two, but structure all more complicated, manufacture difficulty is large, and cost is high, expensive, operating difficulties.
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art, provide a kind of easily manufactured, simple to operate, reliable and stable medical bracket.
Technical scheme of the present invention is achieved in that
A kind of medical bracket, comprise the supporter groove with arch wire groove, arch wire groove both sides are provided with working wing, crossingly with arch wire groove on supporter groove be provided with bracket mouth, working wing is divided into four fritters by bracket mouth and arch wire groove, the working wing of this bracket mouth rear and front end offers front-axle hole respectively, rear axis hole, described front-axle hole, rear axis hole and through bracket mouth crossing with bracket mouth, bracket lid is provided with in bracket mouth, the rear and front end of bracket lid bottom surface is respectively provided with a flange, the flange of bracket cover back-end is provided with slot, the flange of bracket lid front end is provided with open slot, the two ends up and down of open slot form horizontally disposed upper rib respectively, lower stop edge, and the length of upper rib is greater than lower stop edge, in front-axle hole, rear axis hole, be equipped with bearing pin, rear pin shaft before crossing bracket mouth respectively, rear pin shaft is located in the slot of bracket lid simultaneously, and front bearing pin matches with open slot,
When promoting bracket lid backward, rear pin shaft is in the front end of slot, and front bearing pin then departs from open slot and lower stop edge, and bracket lid can overturn around rear pin shaft, now exposes arch wire groove, and arch wire groove be put into or be taken out to arch wire can, and bracket lid is in open mode;
The supreme rib of upset bracket lid rides on front bearing pin in the other direction, driven forward bracket lid again, now rear pin shaft is in the rear end of slot, and front bearing pin snaps in open slot, upper rib, the lower stop edge of open slot are spacing by front bearing pin backstop, bracket lid can not be overturn again open, bracket lid is in closed-lock state.
In order to make bracket lid not be opened easily, as preferably, being provided with at least one at the middle part of slot and spacing arc convex is carried out to rear pin shaft.Being arranged on when bracket lid slides of arc convex adds resistance, prevents bracket lid from use occurring automatically sliding and situation about opening.
As preferably, between the flange and the flange of rear end of bracket lid front end, form one in order to block the slope of arch wire.When bracket lid closes, arch wire can be blocked in slope, prevents it from moving, thus forms active bracket.
The design philosophy of the present invention and the beneficial effect that have employed technique scheme are:
The present invention adopts slide lock tabs structure; bracket covers and normally slides in bracket mouth; bearing pin, rear pin shaft before bracket mouth rear and front end is respectively equipped with; bracket cover back-end forms the slot coordinated with rear pin shaft; bracket lid front end defines the open slot coordinated with front bearing pin; rear pin shaft is located in slot all the time and rear pin shaft maintains static; but along with the slide anteroposterior of bracket lid; rear pin shaft can be made to be in the diverse location of slot; and front bearing pin can snap in or depart from open slot along with the movement of bracket lid, thus bracket lid is made to be in closed or open mode.
Supporter groove of the present invention and bracket lid make simply, and Linear cut can be adopted once-forming, easy to operate.When installing, bracket lid is put into supporter groove, bracket lid can rotate around rear pin shaft simultaneously, opens or closes all very convenient.The troublesome operation of steel ligature is eliminated in clinical practice.As steel ligature or ligation rubber ring, directly can not force in arch wire again simultaneously, therefore the normal movement of arch wire in orthodontic treatment process can not be affected, make orthodontic treatment better effects if.
Because part bracket has certain axial rake, supporter groove of the present invention and bracket lid will have certain gradient, and when bracket lid is opened, bracket lid had both rotated around rear pin shaft; Bracket covers its slot when being pushed simultaneously also has relative sliding with rear pin shaft; Because the present invention adopts slot structure, and slot is open state, and function of the present invention and object are easily achieved.
